ci-lEuuY-'STONEEl SPECIFICATION forming part of Letters Patent No. 724,241, dated March 31, 1903.

Application led July 3, 1901.

To all whom it may concern:

Be it known that I, JOHN G. BAKER, a citizen of Ithe United States, residing in Philadelphia,Pennsylvania,have invented certain Improvemenfs in Cherry-Stoners, of which the following 'is a specification.

The object of my invention is to provide means for varying the throat of a cherrystoner, so that cherries having dierent-sized xo stones can be properly fed through the machine. This object I attain in the following manner, reference being had to the accompanying drawings, in which- Figure 1 is a side view of suflicient of a cherry-stoner to illustrate myinvention. Fig. 2 is a sectional plan view on the line 2 2, Fig. 1. Fig. 3 is a longitudinal sectional View on the line 3 3, Fig. l. Fig. 4. is a transverse sectional View on lthe line 4 4, Fig. 3. Fig. 5 is zo a perspective view of one of the adjustable throat-plates, and Fig. 6 is a view of a modication.

A is a standard for supporting the hopper A', which is made in the usual manner. This hopper is slotted at a for the reception of a wheel B, having trunnions b b mou-nted iu bearingsc on the frame of the machine. One of the trunnions b has a handle B', by which the wheel B is turned. The Wheel has a sego ries of curved ribs b on each side, as clearly illustrated in Figs. 1 and 2, so as to engage the meat of the cherry. f

C is the throat-section of the machine, through which vthe seeds pass, and c is the spout, from which the stones drop after being removed from the meat of the cherry. The meat of the cherry is carried down through the slots a a on each side of the wheel B and dropped into a suitable receptacle in the or- 4o dinary manner.

Heretofore it has been dicult to adj ust the machine t0 stone diferent kinds of cherries in which the stones were of different sizes; but by my invention I am enabled to quickly adjust the machine so that cherries of different sizes will be properly stoned.

Secured at d to the frame of the machine is a spring-plate D', secured in turn to a throat-piece D by means of rivets d in the 5o present instance. This throat-piece is made Serial No. 67.021. (No model.)

as shown in Fig. 5 and has a curved projecting portion cl2, ywhich enters the throat C of the machine. There is one of these throatsections D on each side of the machine, as illustrated in Fig. 2, and on each throat-piece is a perforated lug d3, through which passes a stud e, screw-threaded and provided with a thumb-nut e', so that by turning the thumbnuts the throat-pieces can be moved to or from the wheel B.

The spring-section D' is so formed as to tend to force the throat-pieces out against the action of the thumb-nuts. Thusthe throatpieces are always held rigidly in the position to which they are adjusted.

The construction of the pivoted throatpieces can be varied without departing from my invention, and instead of the spring-plate shown in Fig. 5 the throat-pieces may be made as shown in Fig. 6, in which each throat-piece D2 is made in one piece and pivoted at d4 and separated by a spring d5, although a spring may be used in a similar position to draw the pieces together and nuts may be provided for forcing the pieces apart.

The cherries to be stoned are fed into the hopper A' and the wheel B turned by its crank. The cherries are then drawn into the throat-section C, and the meat is drawn 0E from the stone, owing to the fact that the 8o opening a in the throat-section is narrower than the diameter of the stone. The stones pass through the throat-piece and out through the spout, while the meat is carried with the wheel and discharged iuto a suitable receptacle under the machine. y

If the cherry-stones are small, the thumbnuts are adjusted so as to force the throatpieces toward the wheel; but if the stones are large then the thumb-nuts are adjusted so as to increase the width of the opening and prevent as much as possible the' mashing of the meat of the cherry. Y

I claim as my inventionl. The combination in a cherry-stoner, of 95 a frame having a hopper and a throat-section, said throat-section being slotted, a wheel eX- tending through the slot, a throat-piece on one side of the wheel, yielding means for moving said throat-piece outwardly, and adroo portion extending into the throat of the machine, a spring portion having one end xed to the machine, studs on the frame extending through lugs on the throat-pieces, and nuts on the studs for adjusting the throatpieces and holding them against outward pressure of the springV portion, substantially as described. A

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JOHN G. BAKER.
